So I'm reading green lantern season 2 and I was wondering of I should've read something else before so... Is it part of the main continuity or something and if it is what should I have read before. (I'm new to this so don't judge)
Though it's not titled that for The Green Lantern by Grant Morrison and Liam Sharp
But I don't think you need to read anything prior. Morrison's run is a good place to start. If you're any interested in past Green Lantern stories, stories by Geoff Johns are seminal
